A Wave Glider, an autonomous underwater vehicle, travelled 200 nautical miles of the central Great Barrier Reef recently, in a seven-day trial designed to test its monitoring capabilities and potential for future use.

The new method, developed by the researchers at King Abdullah University of Science and Technology, is more cost-effective and flexible, and it can yield better video quality by improving the bandwidth to stream real-time underwater video images.

More than 535 minutes of footage depicting rarely-seen activities of wild dolphins were captured off New Zealand, in a world-first study involving researchers from the University of Sydney and the University of Alaska Southeast.

The meeting was first proposed by the National Park Service (NPS), then quickly supported by National Oceanic and Atmospheric Administration (NOAA), Divers Alert Network (DAN), and the American Academy of Underwater Sciences (AAUS).

Contact lenses can be displaced, or even lost, if a diver has to remove a mask underwater or hand it up to someone on the dive boat or RIB in order to get back on board after a dive. Masks with corrective lenses can be lost this way.

Nereus was sent to complete the first systematic study of the Kermadec Trench.

Thirty days into the forty-day mission, about seven hours into a nine-hour dive, communications with Nereus were lost. When standard emergency recovery protocols were unsuccessful, the team initiated a search near the dive site. They then spotted several pieces of debris on the surface nearby later identified to be a parts of Nereus, indicating a catastrophic implosion.

The team of researchers focused on the short-term ecological effects of a wind farm in the North Sea. To do so, they analysed the effects of the offshore wind farm near Egmond aan Zee (OWEZ) on benthic organisms, fish, birds and marine mammals.

Fort Pierce, Florida - November 19, 2008 - The Ocean Research & Conservation Association (ORCA) and its collaborators announced today the world’s first use of an acoustic underwater camera to survey juveniles of goliath grouper in mang
